In order to solve many problems in the traditional glass drilling process, a nanosecond green laser was born recently. It is understood that this laser adopts the processing method of galvanometer drilling, and uses the point-by-point action of a single pulse on the base material, and the laser focus moves quickly on the glass according to the predetermined design path to realize the removal of the glass material.

According to Science Daily, any science textbook would probably write that humans cannot see infrared light. Invisible light such as X-rays, radio waves, and infrared light waves all fall outside the visible spectrum.

The 1064nm laser is frequency doubled using a nonlinear optics (NLO) crystal and harmonic separator to generate green laser light. The results show that when the 1064 nm Nd:YAG laser is used for copper micro-welding, pinholes appear, and the absorption rate of the near-infrared wavelength laser increases rapidly, resulting in deep penetration.

A solid-state laser is a laser that uses a solid-state laser material as a working substance. The working medium is uniformly doped with a small amount of activated ions in the crystal or glass as the matrix material. Solid-state lasers have the characteristics of small size, convenient use and high output power. The solid-state laser generally has a continuous power of more than 100 watts, and the pulse peak power can be as high as 10W.

Green laser pointer is a very popular laser pointer at present, because green light is 6 times brighter than red light, the light beam is more obvious than red light, and the price is much cheaper than blue light and yellow light, laser pointer users generally choose green light pointer.

The advent of a laser-guided bullet similar to a dart has set a precedent for unpowered curved flight and directly subverted the traditional shooting principle. This laser-guided bullet is 4 inches long and is suitable for .50 caliber gun family weapons. The laser-guided bullets can automatically adjust their direction during flight, hitting targets more than a mile away like tiny missiles, the researchers said. This kind of bullet can be widely equipped in the army, so as to improve the hit rate of shooting, so that ordinary soldiers also have the magical marksmanship of snipers.

In recent years, with the rapid development of laser technology and the continuous increase of laser devices, more and more types of lasers are available for clinical use, whether it is from high-power continuous lasers to femtosecond ultrashort pulse lasers, or from deep ultraviolet lasers to Mid-infrared lasers all show important application potential in surgery, disease diagnosis, beauty care and so on.

Scientists have recently discovered that irradiating near-infrared laser light on adult stem cells derived from human fat can increase the replication speed of stem cells by 54%, while using green laser light can make stem cells transform into different types of cells at a faster rate. Under laboratory conditions, continuous laser irradiation of adult stem cells results in increased proliferation and differentiation. 

The proportion of fiber lasers in industrial lasers has greatly increased, and they are industrial lasers with a very large market share. For fiber laser technology, it can be used in many fields such as cells, poles, soft connections, liquid injection holes, explosion-proof valves, modules, and tab welding in the production process of power batteries.

With the generation of high-power 10.6µm wavelength carbon dioxide (CO2) lasers and near-infrared 1064nm wavelength semiconductor-pumped Nd:YAG solid-state lasers, high-power CW laser technology has seen the first peak of development.Limitations of NIR Lasers
